L-glutamic Acid,N,N-diacetic Acid, Tetrasodium Salt
Product name: Tetrasodium glutamate diacetate
CAS number: 51981-21-6
Chaical composition: Tetrasodium glutamate N, N-diacetate
Molecular formula: C9H9NO8Na4
Molecular weight: 351.1
Performance and purpose:
Tetrasodium glutamate diacetate is prepared from plant-based raw material L-glutamic acid, which is environmentally friendly, safe and reliable, easy to biodegrade, and meets the requiraents of OECD biodegradability testing.
As a metal ion chelating agent, it can form stable water-soluble complexes with metal ions and can be used in a wide pH range. It has h3 cleaning ability and synergistic effect with fungicides.
It can replace chelating agents such as NTA and EDTA and is widely used in multiple industrial fields, including polymer chaistry, daily chaistry, papermaking, medicine, agriculture, textile printing and dyeing, aquaculture, photographic chaicals, oilfield chaicals, water treatment agents, boiler cleaning agents, etc.
